c# - 红隼错误 : address already in use (dotnet core)

Question

总结:它作为 dotnet run 工作，但它不作为 dotnet myappname.dll 工作。

我的 Linux 技能有限，但我正在努力按照书本进行操作，以免混淆(遵循来自 Scott Hanselman 的 this tutorial):

$ cd /home/myusername/dotnettest
$ dotnet run

Now listening on: http://localhost:5123

然后我将它移动到/var，如下所示:

$ sudo cp -a /home/myusername/dotnettest/bin/Debug/netcoreapp1.1/publish /var/dotnettest

最后我测试它是否也在那里工作:

$ dotnet dotnettest.dll

然后它失败了:

info: Microsoft.Extensions.DependencyInjection.DataProtectionServices[0]
      User profile is available. Using '/home/myusername/.aspnet/DataProtection-Keys' as key repository; keys will not be encrypted at rest.

我一直很小心地试图阻止 nginx。

我已经检查过是否有任何东西正在使用以下命令监听 :5123:

$ lsof -i tcp:5123

似乎什么也没有发生。

以下命令有助于找到端口并杀死进程

mac 上的终端

查找进程号

lsof -i: <port number>

例如 lsof -i:5001

然后杀掉进程号

kill -9 <process number>

例如 - kill -9 1600
